/**
 * @fileoverview
 * some functions for browser-side pretty printing of code contained in html.
 *
 * <p>
 * For a fairly comprehensive set of languages see the
 * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
 * file that came with this source.  At a minimum, the lexer should work on a
 * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
 * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
 * and a subset of Perl, but, because of commenting conventions, doesn't work on
 * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
 * <p>
 * Usage: <ol>
 * <li> include this source file in an html page via
 *   {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
 * <li> define style rules.  See the example page for examples.
 * <li> mark the {@code <pre>} and {@code <code>} tags in your source with
 *    {@code class=prettyprint.}
 *    You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
 *    printer needs to do more substantial DOM manipulations to support that, so
 *    some css styles may not be preserved.
 * </ol>
 * That's it.  I wanted to keep the API as simple as possible, so there's no
 * need to specify which language the code is in, but if you wish, you can add
 * another class to the {@code <pre>} or {@code <code>} element to specify the
 * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
 * starts with "lang-" followed by a file extension, specifies the file type.
 * See the "lang-*.js" files in this directory for code that implements
 * per-language file handlers.
 * <p>
 * Change log:<br>
 * cbeust, 2006/08/22
 * <blockquote>
 *   Java annotations (start with "@") are now captured as literals ("lit")

     * constant like PR_PLAIN.  index_n-1 <= index_n, and style_n-1 applies to
     * all characters in sourceCode[index_n-1:index_n].

     * The stylePatterns is a list whose elements have the form
     * [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
     *
     * Style is a style constant like PR_PLAIN, or can be a string of the
     * form 'lang-FOO', where FOO is a language extension describing the
     * language of the portion of the token in $1 after pattern executes.
     * E.g., if style is 'lang-lisp', and group 1 contains the text
     * '(hello (world))', then that portion of the token will be passed to the
     * registered lisp handler for formatting.
     * The text before and after group 1 will be restyled using this decorator
     * so decorators should take care that this doesn't result in infinite
     * recursion.  For example, the HTML lexer rule for SCRIPT elements looks
     * something like ['lang-js', /<[s]cript>(.+?)<\/script>/].  This may match
     * '<script>foo()<\/script>', which would cause the current decorator to
     * be called with '<script>' which would not match the same rule since
     * group 1 must not be empty, so it would be instead styled as PR_TAG by
     * the generic tag rule.  The handler registered for the 'js' extension would
     * then be called with 'foo()', and finally, the current decorator would
     * be called with '<\/script>' which would not match the original rule and
     * so the generic tag rule would identify it as a tag.
     *
     * Pattern must only match prefixes, and if it matches a prefix, then that
     * match is considered a token with the same style.
     *
     * Context is applied to the last non-whitespace, non-comment token
     * recognized.

     * character, gurantee that this pattern and only this pattern matches.
